I'll mainly be using it for gaming (Diablo 3 currently), picture editing, and remote access. Currently i'm using an old asus p5wdh deluxe with 2gb ram and an old radeon 1800xt, so im need of an upgrade.
The 550TI is a decent video card and should have no problem maxing out Diablo 3, but for more GPU intensive games you might consider going with a stronger video card.
I would also advise forgetting about the SSD altogether if you're planning on using it as your primary boot drive if you cannot afford one that is at least 128GB. The reason behind this is, its very easy to fill up a 60GB drive these days, especially with Windows7 taking up a good 15GB and a single game can easily take 10GB just for one of them, the juggling act required to keep the SSD from filling up would be annoying and outweigh the benefits. Keep in mind and SSD will not improve your FPS or anything like that, it will merely reduce the load time of the game as it boots up the next level, or when it boots up Windows, etc.
